Samba 3.0.25b Available for Download



Posted by: ITKE
Administration, interoperability and integration, Samba

The Samba Team has come through with another production release for Samba 3.025, This is the third production release of the Samba 3.0.25 code base and is the version that servers should be run for for all current bug fixes.

Major bug fixes included in Samba 3.0.25b are:

  • Offline caching of files with Windows XP/Vista clients.
  • Improper cleanup of expired or invalid byte range locks on files.
  • Crashes is idmap_ldap and idmap_rid.

Changes to ‘net idmap dump’:

A change in command line syntax and behavior was introduced in the
3.0.25 release series where the command

$ net idmap dump /…/path/to/idmap.tdb

would overwrite the tdb instead of dumping its contents to standard output as was the case in releases prior to Samba 3.0.25. The changed has been reverted in 3.0.25b and the semantics from 3.0.24 and earlier releases have been restored.

The uncompressed tarballs and patch files have been signed using GnuPG (ID 6568B7EA). The source code can be downloaded
from:

The release notes are available online at:

Linux helps raise money for one million soccer balls



Posted by: ITKE
Linux blogs and news, Linux desktops

I like Linux, and I like soccer (football). So today’s news was almost too good to be true.

Canada-based Omni Technology Solutions, Novell South Africa, Userful, and Pinnacle Micro have teamed up to provide Linux desktop computers for the “Let’s Play a Million” South African telethon on June 27.

The national telethon is a joint initiative of UNICEF, Supersport, the department of education and five radio stations. The objective is to donate a million soccer balls to South African youth and promote child survival through sports and healthy living.

Each of the telethons will be using, fittingly, a grouping of Linux workstations. Here’s hoping they come through! Gooooaaaalllll!

Linux, power management and the green data center



Posted by: ITKE
Hardware issues, Linux basics, Power management

Linux and power managementToday SearchEnterpriseLinux.com ran an article on AMD, Novell and power management, and how the overall Linux community has warmed to the idea of “Green Linux.” Our sister site SearchDataCenter.com has, in my opinion, led the way on power and cooling from a hardware perspective, but today we’re starting to see some of the responsibility on this important issue shift to the software guys too.

Our article today (Novell, AMD synch up on power management) dealt first with AMD and its initiative to shift PowerNow! to Linux systems. Much of the work, said AMD’s director of commercial applications Margaret Lewis, is centered on incorporating AMD’s PowerNow! power management into SLES 10 SP1 and SLES 9 SP4. PowerNow! is a dashboard-based application that conserves power in AMD-based computers. The CPU’s clock speed and VCore is automatically decreased when the computer is under low load or idle to save power and reduce heat, Lewis told me this week.

The AMD news was, obviously, hardware-related, but later in the article we get to the Linux Foundation, and what that group is doing to raise power management awareness with Linux developers. According to the foundation, making Linux green is becoming more important in all aspects of Linux adoption, from desktop to server. At the recent Linux Foundation Collaboration Summit at Google’s Mountain View campus developers said will work to identify key projects and coordinate resources among its members to improve power management functionality in the Linux platform. There’s another meeting scheduled for this week in Ottawa, so we’ll just have to see how fine tuned things become.

Getting Linux, power management, and the data center to coalesce at a single point will be quite the coup if someone can pull it off. Right now, I think each of the factions (hardware, software, etc) are off doing their own thing. Regardless, it’s great to see Linux developers and advocates getting out in front of the issue.

UPDATE, June 26@1:30 pm.:

The world can live without Microsoft



Posted by: ITKE
Linux versus Windows, Red Hat, SUSE/Novell

Linux around the worldIndia. China. Japan. Brazil. Munich, Germany. Russia. The list goes on.

If this were Jeopardy, and I a mustachioed Alex Trebec, that would be the answer. But what is the question? I’ll take the Linux category for $0, please, but remember that’s free as in speech, not beer (the Germans grumble at that one; as I write this, it’s almost Happy Hour in Munich).

The question? Try this: What are some of the nations of the world that have dumped Microsoft Windows in lieu of the Linux operating system?

2006 was full of these kinds of stories. 2007 is shaping up to be more of the same. The countries I named above were but a handful of those named in press releases and news articles spread across the entire Internet last year. In fact, two old story pitches about India’s Tamil Nadu government and a Mexican Mandriva migration currently sit tacked to the wall on my right. Like many things on my desk, they have a bit of dust on them, but the trends contained on their pages persist in other countries today.

China, for example, was in Red Hat’s sight this week. Andrew Hu is the new president of Red Hat operations in China. Hu’s most recent position was president of Asia Pacific for Wyse, a thin client software developer. “Asia Pacific is a key market for Red Hat and we are committed to investing in resources to continue growing our presence in this region,” said Gery Messer, president of Red Hat’s Asia-Pacific Operations.

The move makes economic sense for Red Hat, but finding the same success it sees in other markets will not be an easy task. Red Flag Software Co., for example, is already well entrenched in the Chinese market. According to the China Open Source Software Promotion Union, Red Flag Software ranked first among the local enterprises with a market share of 32.1%. This was higher than both Novell and Red Hat. It will be interesting to see what Hu and Red Hat have cooking for this new landscape. If nothing else, China appears ready to be Asia’s Linux mascot.

I say this because the silver lining for outsiders like Red Hat and Novell is that the landscape is already friendly to Linux, regardless of the source. According to statistics from the China Open Source Software Promotion Union, Linux’s sales in the Chinese market reached 218 million Yuan in 2006, up 41%. In 2006, seven million computers in the domestic market were signed up for pre-installed of Linux, making up 35% of the computers in the Chinese market (perhaps Dell should be taking notes?). According to the People’s Daily Online, “the domestic brand, Linux, has essentially matured.”

Let’s not pigeon hole that maturity sentiment to just China, however. We could just as easily substitute the Tamil Nadu government in India for China’s Open Source Promotion Union. In January, C. Umashankar, managing director of state-owned Electronics Corporation of Tamil Nadu (ELCOT), said his government is fast migrating to Linux operating systems. Cost and security were his motivation. More than 6,500 Linux systems have already been packed off to villages and another 6,100 Acer desktop systems with Novell SUSE Linux were en route. All ELCOT servers will run on Redhat. ELCOT expects to train 30,000 government officials in Linux and Open Office too. The migration is taking place throughout this year.

Japan, too, is wary of Windows. They were so eager to ditch, it seems, that a consortium was formed in May to help them deploy all new open source and Linux systems. Oracle, NEC, IBM, HP, Hitachi and Dell are among 10 IT equipment and software vendors that make up the consortium. The move to Linux in Japan is actually the result of a edict from the country’s government to make Linux and open source a priority for all IT procurements. The program officially begins next month.

An “official edict” from the government to deploy open source. When that kind of thing happens in the States, it usually gets bogged down in hearings and the state government CTO resigns in protest because Microsoft shows up. I would know, I saw it happen almost on my doorstep here in Massachusetts with the OpenDocument Format debate. Who knows where that debate stands today. Peter Quinn is gone, off to enjoy the private sector, and newsworthy ODF announcements haven’t hit my Google Alerts box since 2006.

But those worldwide Linux-for-Windows mass migrations have continued to flow. And it’s all starting in developing countries that will hold some serious weight in 10 to 15 years (or sooner, like China). It’s the reverse effect of what we saw here in the United States and Europe; brick and mortar shops are getting Linux from the get-go, meaning open source is far more accepted in mission critical roles than it would be at a big time American shop. That could mean a leg up on today’s leaders in the near future.

If entire governments — and not just the brick and mortar ones found in Brazil and India — are committing 100% to Linux and open source, I think it begs another question: Is the world ready to live without Microsoft? Munich’s migration foibles make the answer to that question harder to come by, but the rest of the world, it seems, is trying to answer with an emphatic “yes.”

Patch: Linux v2.6.22-rc6 (’knock wood’ edition)



Posted by: ITKE
kernel news, Linux kernel

The headline says it all, plus a little bit more. A new stable patch is out for the kernel.

I’m happy to say that things seem to have calmed down after -rc5, and that most of this really is just bugfixes and regression fixing in particular.

Knock wood.

So nothing really too exciting here, but hopefully we’re getting closer to a real 2.6.22 release. Please *do* test it, and in particular people who have been involved with regressions, please check that the ones that should be fixed are really fixed, and remind people about anything that is still pending. — Linus

Knock wood. Knock on wood. Who cares, right? The man is the the father of Linux for Pete’s sake.

Now that’s tiny — Linux computer on a USB thumb drive



Posted by: ITKE
Hardware issues, Linux basics

Linux USB thumb driveLinux has been known to run on some pretty scaled down hardware over the years, and today’s quirky news item is no exception. Calao, a start-up located in the French Alps near Grenoble is readying a tiny ARM-based Linux single-board computer (SBC) in a USB key form-factor. That Star Trek-type schematic over there on the right is what this puppy will look like when it “launches soon.”

It is based on an Atmel AT91SAM9260 processor, an SoC (system-on-chip) powered by an ARM926EJ-S core clocked at 190MHz. The tiny USB key SBC has 64MB of SDRAM and 256MB of NAND flash. I/O includes a USB 2.0 device port (obviously), a 10/100 Ethernet port, and a pair of USB 2.0 host ports. The device also has a 50-pin expansion interface, although the company has not published the pinout, nor announced any specific daughterboards. Calao says the USB-9260 can be debugged over USB via JTAG and DBGU (“debug unit”). Alternatively an SBC35-A9260 development board (shown below) appears to exist, and to offer a wide variety of I/O, expansion, and debugging interfaces.

Now, what to use this little ditty for? Secret agent stuff? Hiding documents from the public? I dunno. I’ll call up Dick Cheney, see what he’s got cooking for this cute little USB key computer. For now though, here’s what Calao is targeting: “advanced applications such as GPS application processors.”
